The Tour de France is an epic marathon of eating.

The Epic 2,200-Mile Tour De France Is Also A Test Of Epic Eating : The Salt : NPR:

The cyclists now competing in the 101st rendition of the race are burning an average of 700 calories per hour while riding and, to keep their weight up and maintain their health through the three-week event, they must eat 6,000 to 9,000 calories every day.
... The almost nonstop eating begins with juice as soon as the athletes wake, according to Nigel Mitchell, head of nutrition forTeam Sky. After joining their teammates in the hotel dining room, they devour a massive buffet-style breakfast, heavy on carbs and sugar, and moderate in fiber, which can add unwanted bulk to the cyclists' bellies.
When they've finished this matinal meal, they pile into a bus, and keep eating, taking in hundreds more calories in energy drinks and bars before arriving at the starting line. Once they begin pedaling, team support vehicles shadow the riders, and assistants hand them energy gel packets, homemade rice cakes and Panini sandwiches.
